Bidirectional EDFA Amplifier (OPA, OBA) 1528-1568nm

The BEDF Series Bidirectional DWDM Optical Amplifier provides high-performance erbium-doped fiber amplification (EDFA) across the full ITU C-band (1528–1568 nm), supporting high-capacity transmission scales from 2 to 48 channels over a single fiber. Engineered for maximum slot density, the BEDF integrates two independent amplifier stages on a single board to deliver simultaneous bidirectional amplification. Specialized internal photonic components cleanly partition the spectrum, routing downstream traffic (even DWDM channels) through a high-power booster stage, while upstream traffic (odd DWDM channels) is directed through a low-noise pre-amplifier stage. The system features an advanced, software-driven “set-and-forget” Automatic Gain Control (AGC) mode that dynamically adapts pump laser profiles in real time.
